Preface Cisco CRS-1 Carrier Routing System 4-Slot Line Card Chassis Installation Guide xvi OL-10971-07
CH A P T E R 1 Overview This chapter introduces the Cisco CRS-1 Carrier Routing System 4-Slot Line Card Chassis at the highest level. It contains illustrations of the front and back of the chassis, complete with callouts to each hardware component. For details on each subsystem discussed in this chapter, see Cisco CRS-1 Carrier Routing System 4-Slot Line Card Chassis System Description. This chapter also provides the recommended task sequence for installing the major components in the chassis.
Chapter 1 Overview Chassis Components Chassis Components This section lists the main components of a Cisco CRS-1 4-slot line card chassis. It primarily identifies the components that are considered field-replaceable units (FRUs), but where additional detail is useful this section identifies subassemblies that are not field replaceable. Figure 1-1 and Figure 1-2 show the Cisco CRS-1 4-slot line card chassis from both the front (PLIM) and rear (SFC) sides.
Chapter 1 Overview Chassis Components Figure 1-2 Rear (SFC) View of the Cisco CRS-1 4-Slot Line Card Chassis 1 2 AT ST US AT ST US AT ST US US 158296 AT ST 3 1 Fan tray 3 2 AC power plug connectors Switch fabric card slots The Cisco CRS-1 4-slot line card chassis contains the following components: • As many as four modular services cards (MSCs, also called line cards) and four physical layer interface modules (PLIMs).
Chapter 1 Overview Chassis Components • One or two route processor cards (RPs). The RPs function as the Cisco CRS-1 4-slot line card chassis system controller and provide route processing. Only one RP is required for system operation. For redundant operation, you can order a second RP as an option (CRS-4-RP/R). When two RPs are used, only one RP is active at a time. The second RP acts as a “standby” RP, serving as a backup if the active RP fails.
Chapter 1 Overview Chassis Slot Numbers Chassis Slot Numbers This section identifies the location and slot numbers for major cards and modules (primarily the field-replaceable units) that plug into the Cisco CRS-1 4-slot line card chassis. Figure 1-3 shows the slot numbering on the front (PLIM) side of the Cisco CRS-1 4-slot line card chassis.

Chapter 1 Overview Chassis Cable Management Chassis Cable Management The Cisco CRS-1 4-slot line card chassis has cable management features for the front (PLIM) side of the chassis, just above the card cage. The horizontal cable management trays have a special telescoping feature that allows them to be extended when the chassis is upgraded with higher-density cards. This extension also helps when installing the cables in the chassis. Figure 1-5 shows the cable management bracket for the chassis.

Chapter 1 Overview Preventing Electrostatic Discharge Note Review the safety warnings listed in Regulatory Compliance and Safety Information that are applicable to your router before installing, configuring, or troubleshooting any installed card. • Keep the work area clear and dust-free during and after installation. Do not allow dirt or debris to enter into any laser-based components.
Chapter 1 Overview Recommended Chassis Installation Task Sequence Recommended Chassis Installation Task Sequence This section provides the recommended task sequence for installing a new Cisco CRS-1 4-slot line card chassis. Step 1 Step 2 If your system was shipped with AC power, remove the four AC power cords from the box, and do the following: a. Insert all four power cords into the AC power source. b. Insert the power cords into the AC power plugs at the base of the rear of the chassis.
CH A P T E R 2 Installing and Removing Power Components This chapter provides instructions on how to install and remove the Cisco CRS-1 Carrier Routing System 4-Slot Line Card Chassis power components.
Chapter 2 Installing and Removing Power Components About Installing and Removing the Power Components Caution A Cisco router must be operated with all its power modules installed at all times for electromagnetic compatibility (EMC). The Cisco CRS-1 4-slot line card chassis requires that at least the power shelves and their components be installed to operate properly. Two types of power shelves exist: an AC shelf and a DC shelf.

Chapter 2 Installing and Removing Power Components About Installing and Removing the Power Components Note The DC return of this system should remain isolated from the system frame and chassis (DC-I: Isolated DC Return). Powering the Chassis Up or Down The chassis does not have a single enable switch that powers the entire chassis and all its components up and down. (These switches are called enable switches because they enable the power supplies to produce output voltage and power).

Chapter 2 Installing and Removing Power Components DC Power Systems on the Cisco CRS-1 4-Slot Router DC Power Shelf Guidelines At sites where the Cisco CRS-1 4-slot line card chassis is equipped with a DC power input shelf and power supplies, observe the following guidelines: • All power connection wiring should follow the rules and regulations in the National Electrical Code (NEC) and any local codes. • Each DC-input power entry module connection is rated at 60-A maximum.
Chapter 2 Installing and Removing Power Components DC Power Systems on the Cisco CRS-1 4-Slot Router Table 2-1 DC Input Current and Voltage Information Nominal input voltage Supports -48 VDC and -60 VDC systems (range: –40 to –72 VDC) The turn-on voltage of the DC power supplies is -43.5 +/- 0.5 VDC. When a power supply is powered on, it continues to operate down to an input voltage of -40 VDC.
Chapter 2 Installing and Removing Power Components DC Power Systems on the Cisco CRS-1 4-Slot Router Input-Power-Present LEDs The DC power Input-Power-Present LEDs provide a visual indication to service personnel that there is voltage present across the input terminal’s connections (see Figure 2-6). The LED provides a warning to the service person that there is power present. Power should be disconnected before servicing the input power connections.
